Why is there a hissing sound when braking slowly?

Slow braking with a hissing sound is due to malfunctions in the caliper, brake disc, or brake pads. Here are the details: 1. Poor caliper reset can cause prolonged friction between the disc and pad, resulting in abnormal noise. 2. If there are foreign objects inside the brake pads or if the brake pads are too hard (containing too much metal), abnormal noise may also occur. 3. A common reason for the hissing sound during braking is thinning brake pads, causing direct contact between the brake drum and the vehicle, leading to metal-on-metal friction and noise. 4. If the brake pads are installed incorrectly or the wrong model is used, abnormal noise may also occur. The brake pads should be reinstalled, and it is recommended to have them installed at a professional auto repair shop.

What does short-term fuel trim 99.2% mean?

Short-term fuel trim refers to the engine control unit (ECU) adjusting the fuel injection pulse width based on the oxygen sensor readings. If no issues occur, the malfunction indicator light will illuminate when the air-fuel mixture is lean, and the system will adjust it towards a richer mixture. Below are detailed explanations: 1. System Control: During open-loop control, the injector has a fixed base injection pulse width corresponding to the air mass measured by the mass airflow sensor or the load measured by the manifold absolute pressure sensor. This pulse width is adjusted based on factors such as engine temperature and engine speed. During closed-loop control, the pulse width may either increase or decrease, allowing positive or negative adjustments to ensure an appropriate air-fuel mixture under various operating conditions. 2. Air-Fuel Mixture: When the mixture is too rich, the oxygen sensor output voltage increases, and the short-term fuel trim decreases, meaning the fuel injection pulse width will shorten, resulting in a value less than 1 on the diagnostic tool. Conversely, when the mixture is too lean, the short-term fuel trim increases, and the value displayed on the diagnostic tool will be greater than 1.

Where is the headlight washer switch on the Toyota Crown?

Toyota Crown's headlight washer switch is integrated with the windshield washer switch. You need to start the vehicle and turn on the headlights to activate the headlight washer function. Here's a detailed introduction to automotive headlights: 1. Automotive headlights, also known as front lights or LED daytime running lights. 2. As the 'eyes' of a vehicle, they not only affect the owner's image but are also crucial for safe driving at night or in poor weather conditions. Below is the classification of automotive lights: 1. Headlights - Combined headlights located at the front of the vehicle, primarily serving illumination and signaling purposes. They illuminate the road ahead, enabling safe nighttime driving. 2. Taillights - Combined taillights at the rear of the vehicle, mainly for illumination and signaling. 3. Turn signals - Amber-colored lights indicating left or right turns to other road users (required by regulations). 4. License plate lights - Designed to illuminate the license plate for nighttime visibility.

Is the Mustang a Front-Engine Rear-Wheel-Drive Vehicle?

The Mustang is a rear-wheel-drive car. Currently, all Ford Mustang models imported into the domestic market adopt a front-engine rear-wheel-drive design. Here are specific details about the Mustang: 1. The Ford Mustang is a mid-engine two-seater sports car model, with a body design primarily focused on stability for sporty performance. It features characteristic taillight designs, electric mirrors, a keyless entry system, and other rich configurations. 2. Equipped with a MOD V8 engine, the car's output power is increased by 50% compared to the previous generation models. The use of a three-valve cylinder head with VCT allows for a higher compression ratio, maximizing fuel energy efficiency. 3. The original platform of the Mustang belonged to the second-generation North American Ford Falcon. The original Ford Mustang I4-seat concept car was improved into the 1963 Mustang II two-seat prototype.
